Answer 1

The addition of ammonia (NH3) and NH4Cl to watwr produces a buffer solution.

Step-by-step explanation:

Because, to make a buffer solution from a weak base compound, a salt of the conjugate acid can be added.

Because NH3 has a conjugate acid, namely NH4, the suitable salt added for NH3 to become a buffer solution is NH4Cl.
